Scientific paper

It is suggested that compact stars bound to the central massive black hole and orbiting through the accretion disk may produce the giant X-ray pulses that have been tentatively identified with globular clusters. The pulses may be expected to exhibit different types of X-ray behavior, depending on characteristics such as the density and spatial extent of the individual accretion disks at the points at which the orbits of the bound compact stars intersect the accretion disks. Two mechanisms for giant pulse production are proposed. A small, hot shocked area may be expected to be produced twice each orbit as the innermost star passes through the disk. Also, ripples will proceed from the shocked zone towards the center of the disk, producing extra accretion and luminosity when the wave train reaches the innermost stable orbit.
